I have the silver version, and i have been quite satisfied by it. I am ALWAYS poking around with my hardware (i have replaced every drive, CD and HD at least twice and i'm on the second mobo in it), and after 9 months have not had a single screw hole strip out and have no visible scratches on it even after some fairly rough handling (except for the marks that drive mounting screws make... not an issue really).
The only issue with the silver one is finger prints, but a swipe of windex cleans em away.
I have added a chunk of furnace filter media in front of the supplied air filter, and the case stays very clean inside (and has good air movement even when the filters look like a cat).
